Conclusion
In our case, we describe a patient with a pancreatic tumor associated
with a giant hiatal hernia that had prolapsed into the posterior
mediastinum. The patient was safety managed by undergoing hiatal hernia
repair, followed by laparoscopic distal pancreatectomy. In simultaneous
hiatal hernia repair and distal pancreatectomy, understanding the
anatomy is difficult because of the displacement of the pancreas.
Therefore, hiatal hernia repair should be performed first because it
enables laparoscopic distal pancreatectomy to be performed in the normal
anatomical position.
